Peridot is the modern August birthstone and the gem designated for the 16th wedding anniversary.

Peridot (pronounced pair-a-dot) is a transparent yellowish-green Magnesium/Iron Silicate. It is a gem variety of the mineral Chrysolite or Olivine and its chemical formula is given by: (Mg,Fe)2SiO4.

Peridot ranges in color from light yellow-green to the intense bright green of new spring grass to olive. Because of the way peridot splits and bends the rays of light passing through it, it has a velvety appearance, a rich glow, and a slightly greasy luster. The purer green a peridot is the higher the value. Any tinges of brown or visible flaws greatly diminish the price.
